I want to ask. File named hiberfil. Sys what this is for?
The one on drive C.
Hi,
Hiberfil.sys is used by Hibernate mode. Hibernate mode is a kind of power management mode in Windows. It is able to write the memory out to the hard drive and powers down the PC, so you can even take the battery out, put it back in, start back up, and be back where you were.
So it is a file to store the current memory of the PC and because it is managed by Windows, you can delete it.
Here are few steps how to delete it of you are using Windows 7 or Vista:
1. Go to Start menu, then click on Administrator, by right-clicking, click on Run as an administrator.
Type this: Powercfg -h off
2. You should notice that the Hibernate option and the file are not now visible in the Shut down menu.
If you are using Windows XP, it is even easier:
1. Go to Control Panel click on Power Options and find the Hibernate tab.
2. Uncheck the box, reboot your PC, and easily delete the hiberfil.sys file.
HIBERFIL.SYS is a Windows system generated file that is used for Hibernation.
It is created after the computer goes to hibernate and is used when the computer is turned backed on.
The file size varies depending on the size of RAM and the file’s content is the RAM image.
You can only delete the file if you are sure that you will not be using hibernation mode anymore.
To turn off hibernation, follow these procedures:
Windows XP:
Windows Vista/Windows 7:
If I turn off hibernation how to bring it back?
Thanks all It really useful & it helped me out much.
